基于层次数据模型与产品逻辑结构的CAD信息一体化技术

CAD Integrated information technology based on hierar chical data modal and product logical structure

针对传统CAD系统缺少产品技术信息处理功能 ,本文提出了一个基于层次数据模型与产品逻辑结构的CAD信息一体化技术方案。在数据库支持下 ,产品设计过程中的信息得以共享和重用 ,实现了信息的有效管理。通过实际应用 ,增强了CAD系统的功能 。

On the problem of Traditional CAD without product technical information processing, the paper presents a project based on hierarchical data modal and product logical structure. On the support of database technology, the information in product design can be shared, reused and effectively managed, the efficiency and quality of CAD are upgraded.
